I've been using Savitzky-Golay (SG) filters for quite a while, but always on 1D data, using an implementation based on the algorithm from the Numerical Recipes to calculate the kernel (mask, ...
Abstract: In the presented study, training of kernel matrix which is used for convolution or correlation image filtering operations using genetic algorithms was analyzed. For this purpose, filtering ...
Abstract: Nonnegative matrix factorization (NMF) is an algorithm for blind source separation. It has been reported that the use of kernel NMF (KNMF) is a particularly feasible way to extract the ...
